Open Systems Interconnect (OSI) Model: A conceptual structure that standardizes the functions of a communication system into seven distinct categories known as layers. These layers, from highest to lowest, include the application, presentation, session, transport, network, data link, and physical layers. Each layer provides specific services that contribute to overall network communication, fostering interoperability between various hardware and software systems.
